As driving functions become increasingly automated, motorists run the risk of becoming
cognitively removed from the driving process. Psychophysiological measures may provide …

Heart rate data are often collected in human factors studies, including those into vehicle
automation. Advances in open hardware platforms and off-the-shelf photoplethysmogram …

Facial video-based remote physiological measurement aims to estimate remote
photoplethysmography (rPPG) signals from human facial videos and then measure multiple …

Background Photoplethysmography (PPG) is a low-cost and easy-to-implement method to
measure vital signs, including heart rate (HR) and pulse rate variability (PRV) which widely …

The photoplethysmogram (PPG) signal is widely used in pulse oximeters and smartwatches.
A fundamental step in analysing the PPG is the detection of heartbeats. Several PPG beat …

Driver mental workload is an important factor in the operational safety of automated driving.
In this study, workload was evaluated subjectively (NASA R-TLX) and objectively (auditory …

Background: Heart rate variability (HRV) is a noninvasive method that reflects the regulation
of the autonomic nervous system. Altered HRV is associated with adverse mental or physical …

Research has shown that timing is modulated by mental workload, making duration
judgments a measure of cognitive demand, alongside subjective assessments, and …

Objective. Photoplethysmography is a non-invasive optical technique that measures
changes in blood volume within tissues. It is commonly and being increasingly used for a …

Cardiovascular diseases remain the leading global cause of mortality. Age is an important
covariate whose effect is most easily investigated in a healthy cohort to properly distinguish …
